Abstract

Recent results on low mass dilepton measurements from the PHENIX experiment are reported. Invariant mass spectra of phi -> e(+)e(-) are measured for the first time in Au-Au collisions at root sNN = 200 GeV in Run2. In d-Au collisions, the yields and M-T slopes of both phi -> e(+)e(-) and phi -> K+K- are measured. Both results are consistent with each other within errors. In the future, a Hadron Blind Detector will be installed in PHENIX which will enhance our capabilities of rejecting external photon conversions and Dalitz pairs, that will result in a significant reduction of the large combinatorial background.
